COOLING ATTACHMENT FOR EXPLQSIVE-MOTORS.

Specification of Letters Patent.

Patented Aug. 18, 1914.

Application filed July 7, 1913. Serial No. 777,656.

To all whom it may concern Be it known that we, WILLI M F. TiroMr- SON and JOHN Looxnr, citizens of the United States, residing at Biggs, in the county of Butte, State of California, have invented certain new and useful Improvements in Gooling Attachments for Explosivehlotors; and we do declare the following to be a erence marked thereon, which form a part of this application.

This invention relates to improvements in" explosive motors and particularly to means for keeping the same cool when working hard or running fast, the O Q8CtQ0f the invention being to produce a cooling attachment whereby 'by the use of water introduced into the carburetor, the inside cylinders of the motor may be kept cooler than without the attachment. This both saves the wear and tear ontlie motor and also acts as a. big fuel saver and also makes a much lesser consumption of lubricating oil by the motor, and also eliminates about It also is really a time saver in as much as it is not necessary .to stop motors to allow them to cool ofi' after they have been laboring hard as is now usually the case with such motors as are used on tractors or other working devices. 4

A- further object of the invention is to produce a simple and inexpensive device and yet one which will be exceedingly effective for the purposes for which it is designed.

These objects, we accomplish by means of such structure and relative arrangement of the parts as will fully appear by a perusal of the following specification and claims.

On the drawings, similar characters of reference indicate corresponding parts in the several views.

Figure 1 is an outline view of the explosive motor of a motor vehicle showing our improved cooling attachment thereon. Fig. 2 is a sectional view of our improved cooling attachment. Fig. 3 is a sectional view taken on a line X-X of Fig. 2.

Referring now more particularly to the characters of reference on the drawings, the numeral l designates the motor, the numeral 2 designates the-carburetor, while the numeral 3 designates the intake air pipe of the carburetor. l

Our improved cooling means embodies an attachment for the air intake pipe 3 and comprises a-means-for, admitting water to the same by means of the following struc-- ture, namely: "We first provide a tank or other suitable water receptacle 4; having an outlet pipe 5 provided with a'valve 6 at its lower end. This valve 6 projects into the ail-intake pipe 3 ofthc carburetor and is provided therein with ,adischurge nozzle 7. r

This discharge nozzle 7' discharges into an open pipe or other similar receiving receptacle, 8 within the pipe 3, which receptacle 8 hasra discharge, outlet 9 projecting outside.

of the pipe 3. The valve 6 has a needle 'con-' trol stem 6 whereby a desired quantity of water. may be admitted to the discharge nozzle? 7 U In, practice,wi'th the suction of the engine the water will be taken from the receptacle 8 and passed through the carburetor and,

into the cylinder of the motor where it will thoroughly disseminate among the gases therein and have a tendency to lessen the heat of the explosion and also keep the side walls of the cylinder cooler than if not pres ent.

'10 taken from around the exhaust pipe 11- of the motor and connected with the pipe 3 by means of an intermediate screen member 12 whereby the air may be admitted to the pipes 11 and 3. This screen member 12 is tubular like the pipe and is provided with an outer turna'ble sleeve 13 whereby the open s ace may be enlarged or lessened accor ing to the amount of air desired to be taken into the pipe 3.

From the foregoing description it will readily appear that we have produced a cooling means for explosive motors, whereby by l/Ve have also found that in addition "to keeping the cylinders cooler, this water the use of water, the interior of the cylinders may be kept reasonably cool with the attainment of the advantages heretofore noted.

From the foregoing description it will be readily seen that we have produced such 'a 7 device as substantially fulfills the objects of the invention as set forth herein.

While this specification sets forth in de tail the present and preferred construction of the device, still in practice, such devi ations from such detail maybe resorted/to as do not-form a departure' from the spirit water supply, a pipe leading from said" water supply, a valve on the end of such pipe, such valve having a discharge outlet pit-ejecting into said air intake pipe, a receptacle disposed within and across said air intake pipe, such receptacle having an open side disposed toward the inlet end of said intake pipe, said discharge outlet onsaid valve discharging into said open side of said topies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents,

receptacle, the endsof said receptacle being open and projecting outside of said air intalg'e pipe, as" described.

A; device of the character described comprising the combination with an explosive motor having a carbureter and an exhaust' pipe, of an air intake pipe leading from said exhaust pipe and communicating with said carbureter, a" screen covered open- Iin'g in said air intake pipe; a.sleeve mount ed on said air intake pipe and adapted to form'arlcsure for said opening, ajwater supply-pipe having 'a' valve provided with a dischar sa d carb'ureter, a receptacle within said air intake pipe into' which said discharge nozzle 'G 11}pt1S ,-Sa1d receptacle having open ends projecting outside of said air intake pipe, as described. r

In testimony whereof We affix our signatures in presence of two witnesses.
